HL 860 serves as an accessory for flue gas measurements of various oil and gas burners such as HL 352 Test stand for oil, natural gas and propane gas burners. The unit enables, amongst other aspects, the O2, CO, nitrogen oxides and soot in flue gases to be measured at the same time as the flue gas and combustion air temperature are measured. For defined fuels CO2, CO/CO2, excess air, fuel-air ratio, efficiency and heat losses are calculated.
The device includes a remote control unit with display to visualise the measured values, an internal memory for measured values and a thermal printer for fast documentation. A PC can be connected to the USB interface. Power can be supplied either using a rechargeable battery, or from the mains.
